Talk:Mean radiant temperature

To determine mean radiant temperatutre - and being without a black body or a copper globe thermometer - what do I do?

emissivity vs absorptance

In the first sentence, the ability to absorb heat is not also emissivity; rather it is Absorptance. Mrd999 (talk) 13:19, 7 November 2010 (UTC)[reply]

MRT calculation formula

The formulas to calculate mean radiant temperature are wrong, more precisely the previous list is wrong : temperature has to be in °C to use these formulas, not in K. — Preceding unsigned comment added by Daniellou (talk • contribs) 17:52, 24 February 2013 (UTC)[reply]

Thanks for the review and correction. The formulas have to be in °C. --7alberto7 (talk) 19:52, 25 February 2013 (UTC)[reply]

MRT Is Not Just About The Human Body

The first sentence states, "The mean radiant temperature (MRT) is defined as the uniform temperature of an imaginary enclosure in which the radiant heat transfer from the human body is equal to the radiant heat transfer in the actual non-uniform enclosure." Everything in the Universe has a radiant temperature, so I don't see why the human body enters into the definition. This looks like someone confused the term "body" with "human body," but I see this wording has been in this article for more than two years. Pooua (talk) 17:42, 24 November 2014 (UTC)[reply]

Globe thermometer

Is the globe evacuated? If not, what's in there? Either way it'd be helpful to say. Jojalozzo (talk) 15:52, 13 August 2021 (UTC)[reply]

Standard globe MRT formula

The second formula for a standard globe (emissivity 0.95 150mm) appears to be wrong. The parameters above explicitly state that D is supplied in mm. Simplifying 1.1E8/(0.95*150^0.4) should give something more like 1.56E7 as opposed to 2.5E8 (which is the number you get is using m as the unit). 2603:6010:3F0F:5E08:8883:BB89:528:4CA2 (talk) 02:13, 18 April 2023 (UTC)[reply]
